In the privacy of his room, a curious young man discovers the pleasure of urethral play. With a mischievous grin, he begins to gently stretch his urethral opening, inserting a thin, lubed-up finger, moaning softly at the unique sensation. He experiments with different pressures and depths, his cock hardening as he finds his sweet spots. His free hand snakes down to stroke his erect member, a symphony of pleasure coursing through his body as he teases his sensitive urethra.
